Re: re; replacing the screen,
To remove the LCD screens ribbon cable, the thin black line to the right of the screwdriver tip is the cable clamp, this needs to be gently hinged upwards using a very fine flat blade screwdriver to about 40 degrees, full across the top of the connector working from the ribbon cable side, you will find the cable becomes very loose, and easily removed or reinserted. BUT please take care its delicate !!

Automotive electrical connectors typically have a latch to prevent accidental disconnection. Wipe off the connector thoroughly with a rag, and make sure you have a good light available. Examine the connector carefully for tabs that go over hooks - typically they are on the longer sides of the connector. Sometimes the latches require squeezing a lever actuator to pivot the tab away from the hook, but usually you must pull or pry the tab directly off of the hook. Be very careful not to pull too much - just enough to free the hook so you can pull the connector shells apart. You don't want to break the latch.
Perform a recalibration as soon as you notice a problem, to prevent performance errors.
If the calibration problems do not go away you may need to contact Nintendo for technical service or if you think you can replace the screen you self i can give the process to do so...
How to Replace a Nintendo DSi Touch Screen
Finding someone to fix a Nintendo DSi touch screen can be time-consuming and costly. However, with the right tools, you can do it yourself. Even if you've never tried fixing anything until now.
things you'll need:
* Tri-wing screwdriver * Precision Phillips screwdriver * Precision flathead screwdriver * New Nintendo DSi touch screen
Turn the Nintendo DSi over and find the five screws on the edges of the bottom. Take each one out with your tri-wing screwdriver. In the center you will find an additional screw that will need to be removed with a precision Phillips screwdriver. This keeps your battery in place.
Take the battery out. Underneath it you will find two screws that must be removed with the tri-wing screwdriver. After both have been taken out, pull up on the bottom casing to access the motherboard. In order to replace a Nintendo DSi touch screen, this will have to be removed.
Detach the right and left buttons in the top corners by pulling up. Underneath each one will be a spring---make sure you don't lose these. Then remove the four screws in the middle of the motherboard with the precision Phillips screwdriver.
Look for the ribbon attached on the bottom left corner of the motherboard. Take a precision flathead screwdriver and pull up on the black bar that connects the ribbon. You should be able to slide it out by pulling back.
Find the two small connectors that are locked in with two tiny clips on each one. Lift up on all four clips to pull out the underlying connectors. Take out the motherboard and turn it upside down. Now you are ready to replace your DSi touch screen.
Detach the Nintendo DSi touch screen with your fingernails. Pull it away from the adhesive, one side at a time. Take the new screen and peel away the protective plastic before replacing it. Line it up where the old touch screen was and reassemble the Nintendo DSi.
It can be deduced from your problem that there is no longer a contact between the inner touch pad and the outer touch screen,hence the touch is no longer responding.
The solution is to take apart the phone and replace the touch screen,
Here is a detailed disassmbly to assist you in replacing the touch screen;
1.Remove your battery, sim and memory card. Six screws need to be removed. Two at the top of the phone are covered by plastic stickers which will peel off. 2.Run something like a credit card around the join of the battery compartment to release it from the rest of the phone. 3. Two ribbon connectors need to be disconnected. Each one attaches like a plug and socket. Just lever them up to unplug. You'll then be able to lift the two green circuit boards away from the rest of the phone. 4. Remove the six screws you can see and then you can remove the next layer of the phone. 5.Run your plastic tool along the join of the front cover in order to release it. 6.Two ribbon connectors need to be disconnected. Again, each one attaches like a plug and socket. Just lever them up to unplug. 7.Lever the camera out with your plastic tool. It is stuck down lightly with double sided tape and should come away easily. 8.Lift the screen away from the front cover. It should be loose. Next peel away the big black piece of sticky tape. Now slide your plastic tool under the LCD screen to separate it from the green circuit board. It will be stuck down with double sided tape. Once the double sided tape has been released, pull the screen in the upward direction. 9.You should now have the small LCD screen removed. Thanks and take care
I just disassembled one of these this afternoon. They don't seem to have been built to take apart.
I removed the connectors from the display panel end.
The small connectors are designed so that you push down on the little tab while pulling to remove, but when you push the tab the connector drops below the edge of the frame which prevents it from coming out. I had to gently pry out the connectors with a small flat screwdriver from each corner of the frame.
Once you get the small connectors out you can get a better look at the larger connector. It is glued to the frame. When you pry the glue to break it free do it so you are moving the connector to come away from the edge of the board. It will come off with the glue. On mine it peeled away a section of one side of the connector but I think will still work.
I'm not happy with the way this monitor comes apart. Even after taking this one apart I doubt I could take another one apart without the same kind of butchery.
Hi,i think the inner touch pad of the LCD screen is bad and it needs to be replaced,here is a detailed guide to help you disassemble your LG arena;
Tools required: Phillips screwdriver, mobile phone opening tool, plastic tool such as a guitar plectrum or credit card, double sided tape. STEP 1Remove your back cover, battery, sim, memory card etc. Remove the four circled screws.
Run your mobile phone opening tool around the join of the front and back of the phone. Start at the top and then pull the phone apart when you can get enough of a grip. STEP 3 A ribbon connector (circled) needs to be disconnected. It attaches like a plug and socket. Just lever this up to unplug. Next, peel the blue sticker off. STEP 4The circled ribbon connector needs to be disconnected. Just flick the black latch up and pull the orange ribbon away from the circuit board. STEP 5Pull the circuit board towards you. A little force is required but be careful as a cable is still connected to the board and you don't want to damage it. STEP 6on the left is a connector that disconnected when you pulled the circuit board towards you. Remove the screw, in the upper right corner. Disconnect the two ribbons beside the camera. Each attaches like a plug and socket. Just lever each one up to unplug. Lever up the white wire above the battery slot . Remove the blue sticky tape above the white wire. STEP 7Lift away the part above the camera. The ribbon connector needs to be disconnected. Just flick the black latch up and pull the orange ribbon away from the circuit board. STEP 8Pull the circuit board away from the phone. Note that the connectors,disconnect when you remove the circuit board. Lever up the wire at the base of the phone. Remove the 2 screws at the edges of the base . Peel back the silver sticker STEP 9Use your mobile phone opening tool to lever up the metal part bounding the screen . It's stuck down with double sided tape so using a hairdryer to heat the part may make it easier to remove STEP 10Slide something like the edge of a credit card or guitar plectrum under the right edge of the touch screen. Again, this part is held down with double sided tape which may be easier to remove if you heat it up a little first. You should replace the double sided tape when you put the phone back together. STEP 11Lift the touch screen from right to left. STEP 12Lever the two long stoppers out and then use the recesses as levering points to lift the screen out. STEP 13You should now have the LCD screen removed. Reverse the whole procedure for reassembly. The screen costs only 39USD. Thanks and take care
I've done few myself its not that hard really you jsut have to have the confidence to pull bits and expect the odd loud sound to be made when u take the lid apart.
The screen will have a ribbon connector which jsut plugs directly into the motherboard and a (usually black) power connector as long as you notice where the old one plugged into you will be fine.
A few pointers when dissassembling the machine , make sure you take out all the screws even those hidden ones that mybe in the battery compartment or hiding under stickers, make sure you work on a flat surface away from carpet and static electricty , before you touch the insides of the computer discharge any static build up you have by touching metal and when replacing the screen be sure to tuck in the wires so they fit snug in the case so they dont get snagged when you shut the lid.
There are no real secrets really just use common sense and take it slow
Hi -- as you say the rear metal case needs to be removed, best start around earphone connection, use thumbnail or thin stif plastic,ease under metal case in and work across top, then bottom sections then onto the side (on/off)switch there are two plastic "tanges" about one third along then two thirds along that need to be pushed inwards and upwards.The other side again two "tangs" but both these two are in bottom half only, at quarter and half way position.
Please be very careful and dont insert tool to far 2-3mm at very most.
to remove the top screen the back cover actually slides off after removing all the screws from the front, once thats off you can see the ribbon cable coming through the hinge, what you need to do is coil the ribbon cable up into a tight little roll and push it through the hinge it's easier if you pull the two little cables out first. hope this helps
